Nice build from a first class builder....I have that same stock and camo pattern on one of my rifles. I don't shoot nearly as much as a lot of folks, but try to get out regularly, and focus on quality practice. I know if I continue to shoot the same rifle and load over and over, eventually I'll get one that creeps out of the group. I'd I would have shot 5 into one nice bug hole, I would have likely never fired your 7th (the flyer to the left). This is especially true if my ES was low and up to my standards.
Kinda like the old saying, if u hang around a barber shop long enough you're gonna get a haircut. If you keep shooting, you're gonna get a creeper (my term for flyer).
I'd shoot a couple of 3 to 5 shot groups at longer distances and see what those look like. Good luck.
